will 220 gallon crash or bent my living room?

I had a 210 upstairs. It ruined our upstairs and we now have to get it rebuild/fixed or whatever they do. There are stress marks all on the kitchen ceiling. Most houses are 45psi. My 210 was running about 45-60 psi. Your suppose to stay in the safe zone as well , which is 10 psi below your floor maximum. Put it in the basement.

thanks for the info, i acutally calculate by psf (per foot) umm i've posted the info just above so hopefully it would help you out in figuring out if is ok, and the tank is 0.8 - 1.1 ton after water and stuff

What kind of stand are you using? you can always put a sheet of 1" plywood down under the stand, the same size as the stand of course, and that will spread the weight out over a larger area...

I had a 150 on a crappy 75 year old house with wood floors, I made sure to span the floor joist and had no problem. Even with a 1000 lbs of fishing buddies looking at it standing right in front...
Right now I have a 225 setting on a metal stand with all the weight concentrated on 36 sq inches, (4 - 3"x3" metal pads).
If you are unsure then double the floor joists with 2" x 6"s and support them with pier blocks and 4x4 risers...you'll get a tad of flex but that is the floor system working. Without knowing exactly what you have it is hard to tell ya...If the house is of current building practices then you'll be fine.

Figure out the total weight of the tank and goodies, and divide the weight with the actual area that touches the floor. This will give you a "PSI" pound per square inch figure and you'll see it isn't as drastic as it may seem.

If all else fails put it in the basement to start...

1/8"!!?! how can you tell the floor even moved that much?, Hell, I flex a wood joist floor 1/8" when I walk on them...

Outside my bedroom was the bathroom door, without the tank the door rubbed the carpet, with the tank filled up there was a gap under the door.

For peace of mind I would reinforce the joists that support the aquariums weight. You can sister the floor joist by securing another board of equal dimensions to it. This may cost you 50 bucks and a few hours of work, but that is cheap price to pay for peace of mind. Make sure you do this before you add the aquarium load.

oh my gosh...are you sure is psi? from what i know of when talking about floor weights and stuff is always in psf? i know that my tank is 20 psf, i don't know what that'd be in psi, also how old is your house? thanks.

i've read an article about that, they say i'll have to lift the house first before adding the sister joist? to make sure something something... is it nessasary? and how far apart between each sister joists? thanks.

Blah sorry psf. The people who made our house shook their head when they saw the tank up there. My house is only 2 years old. Older houses actually have better support because they overkilled the support. Now they get away with the minimum making most profit and thats why you see these houses go up in no time.

from me doing some calculator work , a 7x2x2' tank (210) gallon weighs 1,827 pounds filled. Add your gravel and what ever else lets say 2,200 pounds to be safe. Thats 78 psf.
I would put it in the basement!

8x2x2 would only be 57psf ( with only 1827 pounds of weight), quite a big safer. Changing the demensions and keeping the height down could possibly keep your tank where you want it

yeah, you're absolutely right about that, i've actually post a reply earlier saying that the older house is actually better then the new ones, mine is 30 years old, and i have no idea what difference it'd make comparing to the new house, all i know is they got better materials, the new one is about "environmental friendly" and i would take much deeper consideration now about putting the 220g in the living room after all the responses, and of course your personal experience with this, also i saw your tank, that's some killer work you did there with the canopy and the new painting, it looks awesome!
